CAUTION: Before you perform any of the following steps, read the Precautionary Measures warning below for your personal safety and to prevent damage to the computer system from electrostatic discharge.

When reseating the memory fails to correct a problem, use the minimum RAM configuration required to determine the exact modules that may be at fault. On the Dell PowerEdge 300 or 500SC server, the minimum configuration is two (2) DIMMs. If there are more than two (2) DIMMs installed, remove all but two (2) DIMMs and test again. If reducing the number of DIMMs resolves the problem, then you have narrowed the problem to one of the DIMMs you removed or one of the DIMM slots from which you removed the DIMM(s). By trying different memory combinations, you can determine the exact DIMM, or DIMM slot that is causing the problem.

In order to run the Dell system diagnostics to correct a problem, the system must be able to complete the POST cycle and boot to some form of bootable media, such as a floppy disk, CD, or hard drive.

Precautionary Measures

Before you perform any of the procedures in this document, read the following caution for your personal safety and to prevent damage to the system from electrostatic discharge (ESD).

CAUTION FOR YOUR PERSONAL SAFETY AND PROTECTION OF THE EQUIPMENT.

Before you start to work on the system, perform the following steps in the sequence listed:

Turn off your computer and all devices.

Ground yourself by touching an unpainted metal surface at the back of the computer before touching anything inside your computer.

While you work, periodically touch an unpainted metal surface on the computer to dissipate any static electricity that might harm internal components.

Disconnect the power cable to your computer, and then press the power button to ground the system board.

Disconnect any devices connected to the computer, including the monitor, from their electrical outlets to reduce the potential for personal injury or shock. Also, disconnect any telephone or telecommunication lines from the computer.

After you remove or replace parts in the system, observe the following notice to prevent damage to the system:

NOTICE: Make sure that all other system cables are connected before connecting the computer to its electrical outlet.
